I'm surprised anyone expected it to work with anything other than Excel.

Also,

Update!

0.60b:
- Acceleration column was accidentally named Column 1. Woops.
- Added "link" checkbox for RelVal NPC. All values for RelVal NPC and Player are the same, so I just put a checkbox in there that enable the sheet to auto-update all these values to match the Player RelVal values.
- Added Price column. If you enable the edit button here, you'll be able to enter a price (in game price), and the RelVal will be automatically calculated off of that. This formula is accurate to within ~7 credits. A few things need to happen before you can use this properly. Price Mod 1 & 2 all need to be set to 1, and RelVal NPC Link enabled. Vanilla uses 25, which causes an error near the 107 million mark caused by wrapping errors. You'll have to re-calculate your prices if you decide to use this. Note price does not take into account the built-in wares. Those will be added to the cost of the ship in game.
